Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention exposes a photosensitive recording medium using a mask original created based on color image information, and develops and develops the exposed color latent image. The present invention relates to a color image recording device that records color images.

[Conventional technology]

Recently, a monochrome laser printer has been used to create mask masters for three colors, and these mask masters are sequentially sent to an exposure device, where a photosensitive recording medium is color-separated and exposed to light through the mask masters of each color. 2. Description of the Related Art A color image recording apparatus has been proposed that transfers a color image by pressing a developer paper onto a medium and records the color image through heat fixation.

That is, as shown in FIG.
00 consists of a mask original printing unit 701 consisting of a monochrome laser printer, and a color image recording unit 702 connected below this mask original printing unit 701. The mask master creation unit 701 has a polygon scanner 712 that emits a laser beam based on color image information, and the laser beam emitted from the polygon scanner 712 irradiates the peripheral surface of a charged photosensitive drum 713 and is applied onto the charged photosensitive drum 713. Draw an electrostatic latent image. The photosensitive drum 713 on which the electrostatic latent image is formed is transferred to the developing device 71
4, the toner image is transferred onto plain paper fed from the paper feed cassette 715, and a mask original plate for three colors is created.

The mask original created here is sent to the lower part of the exposure device 741 through the transport path 716 and is positioned. after that,
The exposure device 741 is moved left and right to form a color latent image corresponding to each color on a band-shaped photosensitive recording medium 742 through each mask original plate. The substantially optical recording medium 742 is the supply roll 7
50 and is wound onto a winding roll 754. The mask original plate after exposure is stored in a storage passage 721 provided above the exposure device 741 and waits for the next exposure. If the mask original is no longer needed after exposure, the switching plate 742 provided on the entrance side of the storage passage 721 is operated to transfer the mask original onto the mask original discharge tray 730 provided on the operation side where the operator is standing. discharge. Also,
On the opposite side of the mask original discharge tray 730, a manual feed tray 729 is provided for manually feeding the mask original.

A pressure developing device 77 is located on the left side of the take-up roll 754 in the drawing.
The photosensitive recording medium 742 exposed by the pressure developing device 770 and the developer paper 760 are overlapped and pressed together, and the latent image on the photosensitive recording medium is transferred onto the developer paper 760. The developer paper 760 is stored in a cassette 761 provided at the bottom of the apparatus, and the developer paper 760 in the cassette 761 is kicked out by a kick-out roller 762 and fed into a pressure developing device 770 via a conveyance path 763. Ru.

The color developing paper 760 that has passed through the pressure developing device 770 is supplied into a paper discharge tray 764 through a conveyance path 780.

[Problem to be solved by the invention]

The photosensitive recording medium 742 is guided by one or more guide rollers from the supply roll 750 and extends horizontally below the exposure device 741, then passes between two pressure rollers of the pressure development device 770 and reaches the take-up roll 754. .

However, it takes time and effort to incorporate the photosensitive recording medium 742 into the apparatus along a predetermined transport path, and in particular, it is difficult to pass one photosensitive recording medium between the two pressure rollers of the pressure developing device 770. The task had to be done by asking the other party difficult questions, which required a lot of effort.

In view of this, the present invention aims to provide a color image recording device in which a photosensitive recording medium can be incorporated into the device with a single touch, and loading thereof is easy and quick.

[Means to solve the problem]

Therefore, the present invention exposes a photosensitive recording medium using an exposure device, sends the exposed photosensitive recording medium to a pressure development device, and superimposes it on a receiving medium in this pressure development device to develop and develop a color latent image. In a color image recording device for recording a color image, a paper feed roll and a take-up roll for the photosensitive recording medium are incorporated into a cassette so that the cassette can be inserted into a casing, and the pressure developing device is divided into two parts. One pressure roller is movable relative to the other pressure roller to form a movable divided body and a fixed divided body, and this movable divided body is configured to move the photosensitive recording in the cassette when the cassette is set at a predetermined position. The surface of the medium opposite to the image forming side is supported and moved to pull out the photosensitive recording medium in the cassette and combine it with the fixed divided body.
